Repeated Medical PG Question- 18

Q- In a case of tuberculosis of the thoracic spine, the earliest sign of cord compression is

         A. Bladder dysfunction

         B. Extensor plantar

         C. Motor weakness

         D. Sensory loss

Answer is B. Extensor plantar

▪️Pott's paraplegia is an appet motor neuron (UMN) type of paraplegia to begin with and the earliest features of Pott's paraplegia are features of spasticity, i.e. increased tone, axaggerated reflexes and extensor plantar.

▪️The order of involvement in Potts paraplegia is motor first,then sensor,and finally sphincter weakness.

Q- Common bone to fracture with fall on outstretched hand is: 

          A.  Radius 

          B.  Ulna 

          C.  Scaphoid 

          D.  Lunate

Answer is A. Radius. 

🔹Common  bone to fracture  when a person fall  on outstretched hand  is Distal Radius 

🔹Various fractures in distal radius and mechanism of injury are: 

•  Galeazzi  fracture  dislocation  (Distal  1/3rd  radius  fracture  with  DRUJ disruption) –fall on outstretched hand with forearm pronation 
• Colles’  fracture–fall  on  outstretched  hand  with  wrist  in  dorsiflexion  and forearm in pronation 
•  Smith  fracture  (Reverse  Colles’  fracture)  –fall  onto  a  flexed  wrist  with forearm fixed in supination y Barton  fracture–fall  onto  a  dorsiflexed  wrist  with  the  forearm  fixed  in pronation 
• Chauffer’s  fracture  (Hutchinson  fracture)  –Compression  of  the  scaphoid against the styloid with the wrist in dorsiflexion and ulnar deviation.

Q-  Shortening of lower limb with adduction and internal rotation is observed in which of the following types of hip dislocation?

          A. Anterior dislocation

          B. Posterior dislocation

          C. Central dislocation

          D. Lateral dislocation

Answer is B. Posterior Dislocation Of Hip

▪️The most common scenario is in motor vehicle accidents (MVA) where the hip is flexed, and the knee is pushed backward by an impact on the dashboard.

▪️Nine out of ten hip dislocations are posterior.

Clinical presentation:

▪️In the clinical examination, the affected lower extremity is usually shortened, adducted, and internally rotated.

• FADIR → Flexion, Adduction and Internal Rotation

• Limb Shortening
